Field Detail

levelNames

protected java.lang.String[] levelNames

Table translating level number to name and the largest entry in the array that is valid. Will be expanded if needed.

numLevels

protected int numLevels

enabledLevelFlags

protected boolean[] enabledLevelFlags

Table of levels that are to be enabled. Accessed directly by the channel. If null, ignored.

logFileLevelFlags

protected boolean[] logFileLevelFlags

Table of levels that are to be written to the log file. Accessed directly by the channel. If null, ignored.

stderrLevelFlags

protected boolean[] stderrLevelFlags

Table of levels that are to be written to stderr Accessed directly by the channel. If null, then the default behavior of writing serious standard levels to stderr is in affect.

Constructor Detail

StandardLogger

public StandardLogger()

Construct a new logger. Configuration is not done now, to allow the logger to be created very early.

StandardLogger

public StandardLogger(boolean makeCentral)

Method Detail

switchLogFile

public java.io.File switchLogFile(java.io.File logFile)
                           throws java.io.IOException

Switch a log file; replacing the old one with a new one.

Throws:

java.io.IOException

configure

public void configure(java.io.File logFile,
             int[] fileLevels,
             int[] strerrLevels)
               throws java.io.IOException

Configure the logger. All current configuration is discarded. This is a simplistic initial implementation that just allows directing to a single log file or stderr on a level basis.

Throws:

java.io.IOException

configure

public void configure(java.io.File logFile,
             java.lang.String[] fileLevels,
             java.lang.String[] stderrLevels)
               throws java.io.IOException

Throws:

java.io.IOException

getChannel

public LogChannel getChannel(java.lang.String facility)

Get the log channel object for a facility. For a given facility, the same object is always returned.

Specified by:

getChannel in class Logger

getLevel

public int getLevel(java.lang.String level)

Convert a symbolic level to an integer identifier, creating it if it doesn't exist

getLogLevelName

public java.lang.String getLogLevelName(int level)

Convert an int to a symbolic level name.
